Track Buffer

Last Wednesday morning we had a class test for our Operating Systems 3 module,
and one of the questions asked what a track buffer is. Today we were going over
the test questions (which in this case meant resitting the test and then marking
it no fewer than three times). The original test was open-book, whereas this time
it was sat without the benefit of reference material, and quite a few people were
stumped as to what a track buffer actually is.

Fortunately, the lovely Colleen’s weekend activities had prepared her for the
question, as she remarked in a text message afterwards.

Thank goodness I went bowling. At least I know what a track buffer is now. x

Strange but true; your hard drive really does contain a couple of those
long inflatable cylinders to stop the read/write head going off the lane and
into the gutter!

(Thanks to C for letting me blog this, and yes, she was kidding, folks.)
